Derry, NHInc. 1827
Derry is a large suburban town along I-93, one of the most populated communities in New Hampshire. The town's position on the Massachusetts border and the I-93 corridor has driven decades of growth. The housing stock is diverse — dense development near the old downtown, suburban subdivisions throughout, and the commercial corridors along Route 102 and Route 28.
For property professionals, Derry is a large, accessible market with enough scale and housing variety to require neighborhood-level assessment. The commercial base, the range of construction eras, and the town's split between the denser Derry and more rural East Derry create meaningful internal variation.
